DRAW-BAR CARRIER.

Appllcatlon filed November 26, 1915.

To all whom it may concern: Be it known that I, IIERBER'I E. VAN Donn, a citizen of the United States, and a resident of the city of Chico 0, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Draw-Bar Carriers; and I do hereby declare that the following is a. full, clear, and exact description of the same, reference being had to theaccompanying drawings. and to the numerals of reference marked thereon, which form a part of this specifics tion.

This invention relates to an improved type of carrier or support for the drawbar on a ca r. and in the particular construction illustrated one wherein the drawbar is con nected at one end to a draft gear and. at its other end has attached thereon a. coupler head which is held properly supported by It is an object therefore of this invention to construct a device adapted for sliding connection with a. guide beneath the car and with the end. of a dra-wbar to permit movement of the drawbar about its pivot and also to permit a longitudinal movement of the drawbar consequent upon variations in the position of its pivot due to movement of the parts of the draft gear to which the drawbar is connected.

It is also an object of this invention to provide a construction wherein a drawbar is so constructed as to cooperate with a'supporting member which has slidable move ment beneath a I car to permit swinging movement of the drawhar about its pivot. as well as longi'tudinal-move|nent thereof due to variations in position of the elements of ,the draft gear to which the drawbar is conneeted.

It is furthermore an important object of this invention to provide in combination with a. longitudinally,movable and pivoted drawbar means for supporting the same in any position of adjustment. thereof.

It is finally an object of this invention to constructa device for supporting the drawbar in all positions of -adjustnient; permitting easy movement of said drawbar into any position and provided with wear plates toobviate to a great extent appreciable wear on the-construction.

The invention (in a preferred form) is illustrated in thedrawings and hereinafter more fully described.

rier element.

As shown in the drawings:

The reference numeral 1, indicates as a Whole the end frame of a car of any suitable ,type, having a platform extension 9., and secured beneath the end of the frame 1,

of the car, is any conventional type of draft gear 3. Mounted Within said draft gear and forming a part thereof and movable against the resisting mechanisms on the insubstantially equal to that of a radius struck from the normal position of the pin bolt 6, of the drawbar. Slidably mounted upon said guide bar 9", is a carrier block 10, pro- .vided in its upper portion with a curved groove or channelli, curved to correspond .with thecurvature of said guide bar 9, and

in the lower portion of said block 10, a straight downwardly directed Tashaped groove or channel 12,. is formed, the axis of which is at right angles to the centralradius of curvature of said upper groove or channel 11.

Formed on the upper portion of the drawbar 5, near the outer end thereof, 15 a. T-

shaped portion 13, adapted to engage in the 110 'T-shaped channel 12, of said earner block to lide therethrough when l gltudinal 4 15, on the lower walls of the groove or channel 12, on which the T-shaped portion 13, of the drawbar rests. Said wear plates are placed within the mold for the block 10, and held in position by pins or integral extensions before the block 10, is cast, and

-zontally about the pivot then the metal is poured into the mold and forms around said wear plates. Wear plates 13, are also rovidcd, recessed into the T- member 13, w ich bear upon the wear plates 15. Pivoted in a lower extension at the end of the drawbar 5, on a pintle' bolt 16, is a lever 17, one end of which bears upwardly beneath the coupler head 8, to hold the same upwardly, and the other end of which is held thrust downwardly to support said coupler head by a compression spring v18, coiled about a bolt 19, disposed vertically in a cored out portion in the end of said drawbar 5, and extendingslidably through a slot in the end of said lever 17.

The operation is as follow s: I

The drawbar 5, mounted upon the pin'tle bolt 6, is capable of swinging in an arc horioint aiforded by said bolt and is capable o a certain amount of longitudinal movement dependent upon I. conditions imposed thereon due to draft and bufiing stresses, causing movement of the yoke 4, in which the'pintle bolt is mounted,

' with respect to the draft gear 3. The slidable car'rier block 10, permits movement of the drawbar both longitudinally and pivot- -ally and when swinging about its pivot, the

slidable block 10, is moved with the drawbararoundfon said curved track member 9, whereas when longitudinal movement takes place the T-portion 13, of the drawbar slides in the-channel 1 2, of the carrier block.

1amaw'aret lat various details of const'ruction may "be varied through a wide raIige'without departing from the principles of this invention, and I therefore do not ,pnrpose limiting the, patent grantedotIiBr- I ..wise"thafn necessitated by the prior art.

' I claim-as my invention:

1,, In a device of the class describedthe -confibination with a car and its draft gear said drawbar slidebly engaging through another channeled portion of said block whereby said drawbar is sup orted from said track in all positions of a justment of the drawbar.

2. In a device of the class described the combination with a car and its draft gear and drawbar ivotally mounted thereon, of a curved tracii member secured to the car, a block channeled for engagement therewith to slide thereon, a T-sha'p'ed portion formed on said drawbar slidably engaging through another channeled portion in said block, said block recessed in said respective channeled portions, wear plates seated in said recesses to bear upon the curved track and upon the T-shaped portion of said drawbar respectively, and means retainin said wear plates associated with said bloc 3. The combination with a car and its drawbar, of a guide member secured to the car, a block slidable thereon, means aflording a slidable connection between said block and drawbar, and a plurality of wear plates recessed into said block for contact with the guide member and said means.

4:. In a device of the class described, the combination with a car'and drawbar thereof, of a guide member secured to the car, a

block slidable thereon having a channel in the underside thereof, wear plates recessed 'into said block to bear upon said guide member, wear lates disposed in recesses in the walls of t e channel of said block, means formed on the drawbar engaging in the channel of said, block, and wear plates and bear upon the wear plates in the channel of said block.

5. In a device of the class described, the

combination with a car and its draft ear and drawbar, of a track member secure to the car, a block channeledfor englagement with said track member and slid ab e thereon, a T-shaped portion formed on said draw bar slidably engaging through another channeled portion of said block, and wear plates -mounted on said means adapted to: contact mounted both on said T-shap'edortionaand within the channeledv portion 0 said block contacting one another to receive the weight of said drawbar supported from saidtreck'f member in all positions of adjustment of -the drawbar'. p

In testimony whereof I have hereunto subscribed my name in the presence of'twp subscribing witnesses.
